I'm currently participating in the HashKard campaign, where it will be necessary to pass KYC. but on the official site there is even no form for sending data ... 
I believe its HASHCARD (hahaha) cause I accidentally join their telegram group
KYC is protection from multi-accounts, if you can prove your identity, and others can not, then you will get more payments!
I agree but they should announce when the bounty starts not at the end. There are people who do not like it
Yes most of the bounty hunters hate sending copy of their ID and passport as well since it is like their identity is being scatter everywhere, sometime there are airdrops also asking for KYC (what the -----?
), get annoyed so I just say pass!!!Asking for ETH wallet is okay but never send ETH to someone with out a valid reason. Check if that person is the real person or maybe their are different in their name.
